Abstract (en)
[origin: EP1283557A1] The leak location method has the anode gas space of the fuel cells supplied with a fuel gas and the cathode gas space supplied with an oxidation gas, with interruption of the gas feed to one gas space and rinsing of the latter with an inert gas, the cell voltages of the fuel cells being monitored and evaluated via a computer (17) coupled to an image screen.
